I have a requirement in which when a rule is changed, the change needs to be reflected immediately without retarting the system. In Drools 5.x we can use the changeset.xml with the knowlegde agent. Now in Drool 6.0 we have Kie API. 1) does Kie support changeset.xml? 2) Upper management don't want to use kie, they want to use jsr94. Does jsr94 support changeset.xml? -- View this message in context: http://drools.46999.n3.nabble.com/Drools-6-support-for-changeset-tp402713...

Drools 6.0 Kie API vs Drools 5.x Knowledge API

by wtang

Hello, I am upgrading from Drools 5.x in which I am using the Knowledge Base API to Drools 6.0. I understand that Drools 6.0 still support the 5.x Knowledge API. I definitely need to upgrade from 5.x to 6.0, but should I change my existing code that was using the 5.x Knowledge API to use the new 6.0 Kie API? What are the pros and cons? thanks! -- View this message in context: http://drools.46999.n3.nabble.com/Drools-6-0-Kie-API-vs-Drools-5-x-Knowle...

For those who integrated drools on GAE, can you please give some feedback on the memory consumption (does it work with a F1 instance)? startup time (initialization of KnowledgeBase) do you serialize your KnowledgeBase objects to datastore? do they fit in 1MB blobs? And more generally, I'd like to know if it's a good idea to use drools on gae also asked on http://stackoverflow.com/questions/23626451/does-drools-work-well-on-google-app-engine?noredirect=1#comment36276948_23626451 Best Regards, Z

Deploy Rules in a separate OSGi bundles

by Ephemeris Lappis

Hello. I'd like to separate cleanly my Drools system into 2 OSGi bundles : 1) the java code that uses the Kie API (6.0.1) and exposes service interfaces to the business part of the applications. Its code relies on someting like : KieServices kieServices = KieServices.Factory.get(); kieContainer = kieServices.getKieClasspathContainer(); KieSession kieSession = kieContainer.newKieSession(name); 2) the rules themselves, just including the kmodule.xml that manages the ksessions and the drl files in their own packages. Let say the first module is S and second is R, while the applcation is A. This build model works nice in my eclipse with correct maven dependancies set from A to both S and R. Classes in the application A calls the service from the S. The kieContainer has resolved as expected the kmodule and associated the rules files for the given packages, and the application can get the ksession for a given name. I'm afraid that the same code won't run as nice as it does when deployed on my Karaf (Service MIX) OSGi environment. I suspect that the KieContainer may encounter some troubles to detect the kmodule.xml in the META-INF and the DRL files out of another jar. Is there anyone with such experiences ? Any advice to do it ? Thanks in advance. Regards. -- View this message in context: http://drools.46999.n3.nabble.com/Deploy-Rules-in-a-separate-OSGi-bundles...

HTTP 401 Unauthorized when using KIE API on Workbench M2 repository

by Patel, Ronak (Autonomy)

I'm having trouble authenticating to access the Workbench Maven repository through the KIE API (kie-ci). My code is the following and fails on the second line with an exception that says something like module not found. I see the more specific 401 error in the local Maven repository in the resolver-status.properties file. KieServices ks = KieServices.Factory.get(); KieContainer kContainer = ks.newKieContainer(ks.newReleaseId("com.hp.pa.sample", "realestate", "LATEST")); I've tried putting in my settings.xml file both suggestions in https://bugzilla.redhat.com/show_bug.cgi?id=1059584#c4 (also saw the preemptive one in https://bugzilla.redhat.com/show_bug.cgi?id=1037556 and other threads/forums and bug reports), but I continue to get the same error. I did some further investigation using Fiddler and I see that the credentials are not being included in the HTTP request the code sends for resources in the Workbench Maven repository. I was expecting the basic authentication header to be in here. The HTTP request always looks like this (server name changed for security reasons): GET http://kiewbserver:8080/kie-drools-wb/maven2/com/hp/pa/sample/realestate/... HTTP/1.1 Host: kiewbserver:8080 Pragma: no-cache Cache-Control: no-cache, no-store Accept-Encoding: gzip Connection: keep-alive Connection: keep-alive Accept: */* User-Agent: Aether And the response is a typical HTTP/1.1 401 Unauthorized with the standard JBoss error page as the body. Using the composer feature in Fiddler, if I issue this same request with the basic authentication header included, it works, returning an HTTP 200 response with the requested file. If I remove the authentication requirement from the Maven repository using the workaround described in bug 1059584 (referenced above), all my code works fine. I followed the procedure to create a user for the Workbench on JBoss AS that is demonstrated in the start of this video: http://www.youtube.com/watch?v=vj3MNmiUnvY. That's the user whose credentials I've tried putting in my settings.xml. Is there anything else that needs to be done on the server side? Any other ideas on what I may have missed or how to debug this further? Thank you, Ronak Patel Software Designer HP Autonomy

NullPointerException when calling ScoreDirector.beforeEntityAdded with new Vehicle

by Hagai

Using OptaPlanner 6.0.1.Final with problem like vehiclerouting. In vehiclerouting the Vehicle and Customer are both planning entities. They both implements the Standstill interface that is annotated with @PlanningEntity and their collections are annotated with @PlanningEntityCollectionProperty on the solution class. Flowing the code of VehicleRoutingPanel.insertLocationAndCustomer to insert a new Vehicle to the solution, my code is failing when the new Vehicle is reported to the score director: scoreDirector.beforeEntityAdded(newVehicle); The exception is NullPointerException at org.optaplanner.core.impl.domain.variable.listener.PlanningVariableListenerSupport.beforeEntityAdded(PlanningVariableListenerSupport.java:54) It looks like the PlanningVariableListenerSupport.entityVariableListenerMap does not have item for the Vehicle entity, there is only one item for the Customer entity in this map. I get the same problem when calling ScoreDirector.beforeEntityRemoved to remove a Vehicle. Is this a bug or do I need to handle Vehicle entities differently? -- View this message in context: http://drools.46999.n3.nabble.com/NullPointerException-when-calling-Score...
